It is one of the most cost-effective ways of saving energy and helping reduce heating and cooling bills. In addition, it adds to the thermal and acoustical comfort to your home.

Cellulose insulation is made of recycled paper products, primarily newsprint, treated with fire-retardant chemicals like boric acid. The paper is ground into a fibrous material that traps air, providing thermal resistance. This eco-friendly insulation is commonly used in walls and attics for energy efficiency.

First priority should be the attic, followed by the exterior walls, basement and/or crawlspace. Additional areas that need insulation include kneewalls, kneewall floors, sloped walls, cathedral or vaulted ceilings, and cantilevers.

The amount of insulation installed is specified by an R-Value. This is a measure of the ability for the insulation to resist heat traveling through it. The “R” stands for resistance to heat flow. The higher the R-Value the better the thermal performance. Different climates and locations can require different R-Values.

Cellulose insulation can get moldy if it stays wet for an extended period. While it is treated with mold inhibitors, prolonged moisture can still support mold growth. Proper ventilation and moisture control are essential to prevent mold in cellulose insulation.

In the Attic, at least an R-49, exterior walls R-15 and basements and crawl spaces R-21

Cellulose insulation can be used in old homes with plaster walls by installing it through small holes drilled into the wall cavities. This method, known as drill-and-fill, allows dense-pack cellulose to fill gaps without removing plaster, improving energy efficiency while preserving the original wall structure.

We use blown Class I Cellulose called Green Fiber Sanctuary. Cellulose insulation is an excellent choice because it is eco-friendly, made primarily from recycled paper, and treated for fire and pest resistance. It provides superior thermal performance, effectively sealing gaps and reducing air infiltration for better energy efficiency. Its dense composition also enhances soundproofing, creating a quieter and more comfortable home. Plus, it’s a sustainable option that reduces environmental impact while delivering long-lasting insulation benefits.

Cellulose insulation is generally safe for people with allergies because it is made from recycled paper and treated with non-toxic additives like borates, which resist mold and pests. However, during installation, dust may cause irritation, so wearing protective gear is recommended.

You can stay home during insulation installation because the process is minimally invasive and generally quick. Insulation is installed using equipment designed to contain dust and debris, ensuring a clean and safe environment. Nealon also takes precautions to work efficiently and respect your space, allowing you to go about your day while the work is completed.

The main difference between cellulose and spray foam is that cellulose is made from recycled paper and offers good thermal performance at a lower cost, while spray foam provides a higher R-value per inch and acts as an air barrier. Spray foam is more expensive but seals better against drafts.

If the insulation existing in an attic space is batting, we bag, seal and haul it out of the attic space. If the insulation existing is blown, we use a Hepa Vac System, in which we vacuum out from the attic through a hose the insulation, which is collected in a Hepa vac bag outside the premises and hauled away.

Cellulose insulation can settle over time, especially if not densely packed during installation. Settling reduces coverage and creates air gaps, which lower thermal performance. Proper installation using dense-pack techniques minimizes settling and helps maintain effectiveness over the life of the insulation.

Yes, we would first ask when your house is built as that is a determining factor. Building codes started in 1971 in Connecticut so anything prior most times is empty unless renovated, but in between years may so we can provide you with a wall test. This is where we would remove a couple rows of siding or pieces of clapboard, drill a 2 1/8” hole to see what is inside and replace the siding. We can add here, we usually charge $150 for a wall test, which we would credit to the job if they were in need of insulation and went with us. You can also choose to get an energy audit to have a blow-door test to find out your insulation needs. This is related to the insulation rebates available and more information can be found at energizect.com.

Cellulose insulation is generally less expensive than fiberglass. It offers comparable thermal performance at a lower cost, especially for retrofitting older homes. While installation methods differ, cellulose is often more cost-effective due to its recycled content and ease of application.

Yes, you can visit energizect.com for more information on the current available programs. Qualified homes can currently receive $1.70 per square foot rebate on attics, walls, garage ceilings (with room above) and rim joists, along with an $.80 per square foot rebate on basements and crawls. This rebate can vary, so check the website for the latest information.

Cellulose insulation does not attract mice despite being made of paper because it is treated with borates, which act as a pest deterrent. While no insulation is completely rodent-proof, the chemicals used in cellulose make it less appealing for nesting compared to untreated materials.

Yes, you can claim a 30% tax credit for the products purchased and installed, up to a $1,200 maximum credit. See your tax preparer for details.

Yes, cellulose can be used effectively in both ceilings and floors as an insulation material.

We also do insulation removal and venting. We can install gable vents, ridge vents, roof and soffit vents.

In Connecticut, cellulose insulation should be a minimum of 10–11 inches thick to meet the building code requirement of R-38 and 14 inches thick for R-49, which is recommended for better efficiency and comfort. Always measure thickness after settling and check local codes for specific requirements.
